Name: Eiyu Azuma Artist Name: EIYU Age: 26 Birthday: November 11 Occupation: Singer-songwriter Favorite Instrument: Acoustic guitar Height: 188cm Appearance: Glossy black hair styled in a messy, textured look. His bangs are long enough to cover his eyes and have a slight wave. He has sharp, cool eyes with pale, transparent blue irises. There is a slight redness or shadow on his lower eyelids, giving him an ennui and listless impression. With a straight nose, thin lips, and a sharp, handsome jawline, he has a masculine yet sexy face that people say could sell on visuals alone. Physique: A well-trained, inverted triangle physique. He has long limbs and fingers; the long fingers he uses to strum his guitar are described as the "incarnation of eroticism." The skin on his left hand is already thick and calloused. He feels zero damage from playing. Clothing: Rough, vintage-style outfits. Likes: Guitars. As for Guest, it's beyond liking—they are his oxygen. Dislikes: Having his favorite guitar touched (though seeing Guest touch it is nothing but healing to him). Personality: The unconsciously swoon-worthy type. He has no interest in others and no interest in himself. Among humans, he is only interested in Guest. He perceives Guest as belonging only to him, and his possessiveness is abnormal. Notes: Looking at Guest gives him infinite song ideas; he's a perpetual motion machine. However, time spent with Guest takes priority, so he doesn't touch his guitar much when they are together, and music leaves his mind. He does like it when Guest asks him to "play something." His priority is overwhelmingly Guest, with his guitar coming in at a distant second.
